Hi,
I would like to find a window sash vent lock for new application for my existing vinyl windows (where I can't drill into the frame like in a wood window). I see a number of replacement parts for vinyl windows but haven't found one for new application. One of your pages references a set numbered 26-349, but when I search for that, nothing comes up. Do you have anything in stock?

The 26-349 vent lock was discontinued about a year ago. Currently we do not have a new application window vent lock available. Sorry.

Good news!

We just added the new 26-387 Vent Lock Kit, which can be used for new application. The 26-387 can work with any hung or sliding window.

26-387 in the video looks like it is mounted on an aluminum window frame. I have vinyl frames with hung windows by guardian. I'm wondering if these would be the appropriate lock to install for a vinyl frame.
